ULYSSE BOUGHER, OF PARIS, FRANCE.

APPARATUS FOR DE CORTICATING AND CLEANI NG GRAIN.

SPECIFICATION forming part of Letters Patent No. 225,329, dated March 9,1880; Application filed J anna-ry 5, 1880. Patented in England, May 28,1878.

To all whom it may concern.-

Be it known that I, ULYssE BOUCHER, of Paris, Republic of France, haveinvented certain Improvements in Machines for Hulling and CleaningGrain, for which British Letters Patent No. 2,117, dated May 28, 1878,were granted to William Spence, as a communication from me, and of whichthe following is a specification.

The object of my invention is to construct a simple and efi'ectivemachine for hulling and cleaning grain; and this object I attain in themanner which I will proceed to describe, reference being had to theaccompanying drawings. in which- Figure 1 Sheet 1, is a side view of themachine; Fig. 2, a plan view with the crankshaft, bearings, andconnecting-rods removed and Fig. 3, Sheet 2, a transverse verticalsection.

'The apparatus is composed of a longitudinal box or trough, A, the shapeof which is shown in Figs. 1 and 2. In this box operate three plungersor pestles, B, connected by rods G to the cranks on the crank-shaft D.They are of a trapezoidal form, are rounded at the lower end, and arecovered with punctured sheet metal.

The frame of the apparatus is composed of vertical posts E, of wood,connected at the up per part by cross-bars F, which support the bearingsGr of the crank-shaft.

The pestles are guided in their vertical motion by slides H, sliding onmetallic rods I,

of a cylindrical brush, both placed below the apparatus.

It is not indispensable to wet the grain for the purpose of hullin g itbut if it is not wet the operation is longer.

I am aware that it is not new to combine reciprocating plungers orpestles with receptacles for decorticating grain. This, therefore, I donot claim; but

I claim as my invention- The combination of the longitudinal troughadapted to receive the grain at one end and having an outlet at theother end, with a num ber of plungers adapted to work in said trough,and connecting-rods, crank-shaft, slides, and guide-rods above thetrough, all substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

- Witnesses: BOUOHER ULYSSE.
